Abstract
An apparatus according to the present invention in which a first substrate including a photoelectric conversion element and a gate electrode of a transistor, and a second substrate including a peripheral circuit portion are placed upon each other. The first substrate does not include a high-melting-metal compound layer, and the second substrate includes a high-melting-metal compound layer.
Claims62
A photoelectric conversion apparatus comprising:
- a first semiconductor layer;
- a second semiconductor layer including a source region and a drain region of a transistor, the transistor having a gate electrode disposed between the first semiconductor layer and the second semiconductor layer;
- an insulating layer disposed between the first semiconductor layer and the second semiconductor layer;
- and
- a silicide which is provided on at least one of the gate electrode, the drain region and the source region of the transistor.
